Kling 3.0
Strengths
- +TWO MODELS: V3 = prompt-driven (3+ characters, AI Director, structured storytelling)
- +O3 = reference-driven (Elements 3.0, video character refs 3-8s, Signature Voice binding). Native 4K at 60fps. Multi-shot up to 6 camera cuts with per-shot control (duration, size, angle, camera movement). Native lip-sync in EN/CN/JP/KR/ES + dialects + bilingual code-switching. Motion Brush for drawn motion paths. Best text rendering in AI video (signs, logos, price tags). Character identity lock across shots. Start/end frame conditioning.
Trade-offs
- -Multi-shot not compatible with first/last frame feature. O3 optimized for 1-2 elements (V3 better for 3+ characters). Credit pricing: 12 credits/sec for 1080p+audio, 9 credits/sec for 720p+audio. Audio can be less refined than Veo. Transitions between shots can be clunky. 15s max duration.
